Representative books include:

Originally published in 1993 and now in its 12th edition, this remains the best selling
book about the Internet, and the a popular way for new users to get on-line.

flex & bison
describes two popular tools used for writing compilers and text analysis tools.
It is a revised edition to the classic 1992 lex & yacc, which we think stayed in print
longer than any other computer trade book.

This book guides network and server managers through the process of installing the
qmail package and configuring it for a variety of e-mail applications.

Mobile Internet for Dummies (Wiley Publishing, 2008).
A topical For Dummies book just about using the Internet from phones and
other mobile devices.
It includes advice on using popular mobile services including the Web
and E-mail, popular applications including search, instant-messaging,
and online entertainment, along with a unique section on creating your own
online mobile presence.

Linkers and Loaders (Morgan Kaufmann/Academic, 2000).
Linkers and loaders are programming development tools that have been in use since the late 1940s but,
remarkably, never the subject of a book until now.
This book quickly became the standard reference on the topic.
